DigiTech RP250 - Vibrato and Rotary Speaker Effects; Vibrato and Rotary Speaker Parameters

29
Depth - Knob 3 adjusts the Depth of the modulation. Ranges from  to .
Regeneration - Knob 4 controls the regeneration of the effect. Ranges from  to .
Waveform (X-Edit
TM
only) - Selects a waveform: , , or .
Level (X-Edit only) - Controls the level of the effect. Ranges from  to .
Vibrato ()
A Vibrato effect modulates the pitch of the incoming signal at an even rate.
Speed - Knob 2 adjusts the rate (Speed) at which the pitch modulates. Ranges from  to
.
Depth - Knob 3 adjusts the intensity (Depth) of the modulating pitch. Ranges from  to
.
Rotary Speaker ()
Rotary Speaker is an emulation of a device that included a spinning horn and woofer. The rotation
of these two speakers produced an interesting combination of the sound panning from side to
side. This produced a slight pitch change due to the speed of the sound coming towards, and then
going away from the listener.
Speed- Knob 2 adjusts the rate (Speed) of the spinning speakers. Ranges from  to .
Intensity - Knob 3 controls the intensity of the effect. Ranges from  to .
Doppler - Knob 4 controls the Pitch Shift effect that is the ratio between the horn and the
rotor positions. Ranges from  to .
Crossover (X-Edit
TM
only)- Selects the crossover frequency between the horn and rotor.
Ranges from  (200 Hz) to  (1600 Hz).
